Yes, TTI's don't fit , I went with headmans for that reason but they fit like crap in other places....  You will need both the pitman and idler.  The different part #s are because of small or large sector shaft boxes.

The Flo Tech headers fit with a big block, if I get the 1-3/4" with 3" collectors should they match up to the TTI 3" exhaust I selected? How are Flo Tech headers? If they won't match up or they're not very good, I'm thinking I may just go with the upgraded Hotchkis steering rod kit instead and skip the fast ratio arms. Or can I have both the arms and the rods?

I have no idea if Flo Techs fit? Email FF and ask?  Bu steering rods kit I assume you mean the tie rod replacement kit ? If so yes you could use both, one is for faster steering the other is supposed to help with bumpsteer?

Yes that's what I meant, cool. Well, I guess I'll just have to see if the Flo Tech headers will match up with the TTI exhaust

The Flow Tech headers should match up, however, it says that the headers won't work with vehicles that have power steering...should installing a Firm Feel Stage 2 or 3 box or a Borgeson P/S conversion fix this problem?

I doubt it? Sounds like they are for a manual box?  :dunno:

Why don't people use a steering quickener, like hotchkis,  instead of the TA arms?

It's an option, but requires you to cut up your steering column. It's not as easy as the fast ratio arms it's a bit of work to fabricate.

Ugh, well that's annoying. I'll keep searching for headers that work with the fast ratio and power steering.

Hedman makes some heavy duty thermal coated big block headers which will clear both the power steering and the fast ratio arms, question is, are they made for 550-650 horsepower and foot pounds of torque. The part # is 78038 HD

By the way, been meaning to ask, is there much difference between manual and power steering? In performance, MPG, weight, anything? And what would be considered a large or small sector shaft?

That's the same headers I have and they don't fit well. Others have had those headers and fit with no problems? Steering... power is power assisted easier to turn manual is not harder to turn especially in parking maneuvers/tight quarters such as autocross racing, more so with fast ratio arms I'd imagine.  Pro's to manual are  the box is smaller and lighter and no parasitic HP loss from power steering pump. The steering column shaft is different between power and manual ( different lengths) Pesonally I have no experience with the Borgeson box  BUT have read lots of posts on here and Moparts where the mounting plate is welded on crooked causing issues and the pitman arm spline engagement is an issue. Personally I have an issue with welded steering boxes. There are very few welders I'd trust with welding  a steering box that could effect my life and my investment, but that's just me and my opinion. 
Small sector shaft was 70-71 in ebodys 72 ( I think ) and up is large sector shaft. Large sector shaft box is more plentiful and pitman arm is cheaper when buying stock parts.

Glad to see you stop thinking about the g-max and similar setups. To properly install one is tricky, as you have to slice your uni-bodies frame rails in half, cut up your floor pans to clear, as they are the "guide" for positioning the body over the frame. In doing so if the body isn't properly braced you stand a very good chance of permanently damaging the body. As far as stiffening the current car it never ceased to amaze me the difference a good set of sub-frame connectors will make, yeah you can feel it. Especially the triangulated type. There are many products for the front of our cars, to really tie it together, a 6 or 8 point roll bar does wonders for getting the last bit of flex out. Lastly, you could try the new flaming river power steering box, its a fast ratio and is half the factory box size, bit as with any thing "bolt on" you may have to put some effort into making it fit.

" you could try the new flaming river power steering box, its a fast ratio and is half the factory box size,"  got a link? First I've heard of a new power steering box? I went to there site but couldn't find it? Just the manual box?

Sorry brain fart, Borgenson box. Was looking at flaming river earlier as well. Mix matched the two.

Well, guess I'll just have to try those headers out when the time comes. So for a power steering box you'd recommend a Firm Feel Stage 3? What's the difference between stage 2 and stage 3? And I was told that power steering usually had a large sector shaft and manual had a small one...are there any pros to power steering over manual?

The Borgeson is half the size? That's great, the headers will probably have a much easier time clearing. How does the Borgeson compare to the Firm Feel? And does it use a large or small sector shaft? I've seen two sizes, 1-1/8" and 1-1/4"
